MACHINE FOR PACKING COTTON.

SPECIFICATION forming part of Letters Patent No. 403,734, dated May 21,1889. Application filed June 23,1888. Serial No. 277,940. (No model.)

To all whom, it may concern:

Be it known that I, FARLEY BRADY, a citizen of the United States, and aresident of \Vaxahachie, in the county of Ellis and State of Texas, haveinvented certain new and useful Improvements in Cotton-Packers; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, refereneebein g hadto the accompanying drawings, which form a part of this specification,and in which Figure 1 is a side elevation of myimproved cotton-packerwith a portion of the supporting-frame, and also with a port-ion of theI)1'6SS-l)OX, shown broken away to more clearly illustrate the characterof my invention; and Fig. 2 is a top plan view of the-same.

Similar letters of reference denote corresponding parts in both thefigures.

My invention has relation to that class of devices known ascotton-packers, which pack the cotton preparatory to baling the same 5and it has for its object to provide means whereby a powerful pressureis exerted upon the cotton while in the press-box, and also to soconstruct the packer that a great amount of labor is saved.

To this end my invention consists in the improved construction andcombination of parts of the same, as will be hereinafter more fullydescribed.

In the accompanying drawings, the letter A denotes the frame upon whichmy invention is mounted, but the construction of which may be changed atpleasure. This frame consists of the posts or uprights 13, secured uponthe base-piece O and connected together by the longitudinal beams I) andcrossbeams D.

F indicates the press-box of ordinary construction, within which thefollower-block slides. This block is secured to averticallyreciprocating rack-bar, H, by means of two angular metallicstrips, I. (Shown in Fig. 1 of the drawings.) This rack-barreciprocatesvertically, and is guided by brackets J, secured to two of thecross-beams D. Each of these brackets is formed with arms K, pointingtoward each other and provided with an anti-friction roller, L, whichengages the rear flat portion, M, of the said rack-bar, while the armsof each bracket engage the opposite flat portion, as shown in Fig. 2 ofthe drawings. Thus it will be seen that the said rackbar will be guidedup and down and be prevented from moving laterally, which would cause itto be thrown out of gear with its meshing wheel, and it will also beseen that by the employment of the anti-friction .rollers friction isreduced to a minimum.

Journaled in two bearings, N, secured to the longitudinal beams of theframe, is asha'ft, 0, having keyed thereon two cog-wheels, l and Q,respectively, the large one of which, I, meshes with the follower-blockrack-bar, while the smaller one meshes with a similar rack-bar, R,moving vertically in a bracket, S, precisely the same in construction asthe brackets which guide the follower-block rackbar. This rack-bar Rreceives motion from a piston inclosed within the steam-cylinder T,

the rod of which piston is secured to the lower end of the rack-bar. Thecylinder is supplied with steam in the well-known manner, andconsequently it is thought that an illustration of the valves andsteanrchest will not be required, as they do not form in themselves anypart of my invention.

It will now be seen that as the shaft is made to revolve by thesteam-actuated rackbar engaging the small cog-wheel the larger wheel,which is keyed to the smaller one, revolves in unison with it andengagesthe follower-block rack-bar, causing the block to be forced downwardlyupon the contents of the press-box with a greater speed than thesteamactuated rack-bar moves upwardly, thus imparting a powerfulpressure to the followerblook. Upon the downward stroke of the pistonits rack-bar is lowered and the follower-block rack-bar is raised toenable the person feeding the pressbox to place more cotton therein.

From the foregoing description, taken in connection with theaccompanying drawings, the operation and advantages of my invention willbe readily understood without rcquiring an extended explanation. It willbe seen that the invention is simple in construction, not liable to getout of order, and performs its dutyiu an exceedingly efficient manner,whilc it takes only one person to work it.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States In a cotton-packer, the combinationof the frame, guides mounted therein, rack-bars moving in the saidguides, a press-box and steam-cylinder, and heads secured to therackbars and moving in the press-box and cylinder, respectively,cog-wheels of different diameters journaled in the frame and meshingwith the rack-bars, and anti-friction rollers pivoted in the guides andbearing against the raclebars, substantially as and for the purposespecified.

In testimony that I claim the foregoing as I 5 my own I have hereuntoaffixed my signature in presence of two Witnesses.

FARLEY BRADY.
